Just back from a trip on one of the search vessels. Talk to me about how difficult it is the conditions out there, the search for the wreckage and the victims. Its been slowed down by this rough weather. Reporter anderson you can see its glorious weather on land here at the moment. That Means Nothing out there. The military helicopter thats taking off behind me right now, a group of muslim clerics on board, a group of imams who will fly over the search area and say a prayer for those victims who lost their lives in that airasia crash. Now, on sunday we had a chance to get right into the middle of that search area sector four, with one of the search and rescue boats and see exactly what those weather conditions were like. Theyre not good. Sunday was supposedly better than most other days but it was still very windy. The wind the waves were very high. The crew was looking out to see if they could see anything with the naked eye. I was looking as well. And if you saw something, it could disappear within a second behind a wave. And then you wouldnt see it again. It is very challenging. One of the crew members did spot something. They called it in. Then another larger boat came and picked up a seat from the aircraft showing just how important it is that they do have plenty of eyes on the surface of the water. But, of course its under the water that they really want to get to see. We know the u. S. Is deploying sonar at this point. Divers are struggling. Zero visibility were being told. As you can see with these conditions we saw on sunday just how choppy this sea is. You dont expect it to be calm. It is the middle of the java sea. But this is the middle of the monsoon season and officials here are telling me the weather is by far, the biggest obstacle in this operation. Anderson . I understand the ship you were on relatively small from the other craft out there, you had to turn around after completing only half of the mission. Reporter thats right. The mission was to transfer a pinger locater to one of the larger ships thats able to stay out at sea the entire time. They just about managed to do that. The expert who was supposed to jump across between ships didnt in the end because the ships were banging together and it was simply too dangerous. They also tried to get the inflatable boat across which is needed to operate this pinger locater. That failed as well. So we know theyve headed out again on monday to try and carry out that mission. The largest ships are doing the bulk of the work here. We know the u. S. Has two ships out there at the moment. Helicopters on board. Its a Real International effort. Youve got russia france australia, malaysia singapore, to name a few, with a lot of assets in this search. Unless the weather significantly improves all the best equipment in the world really has some serious limitations, anderson . Yeah. Appreciate the update paula. Paula hancocks. Some very difficult condition ss. They can do what divers often cannot. However, Stephanie Elam reports even these maritime versions are not super human when it comes to operating in rough waters. Theres no line to the surface. Theyre totally autonomous. 1600 pounds of technology plastic and foam withstanding the pressure of diving 20,000 feet below the surface. This 3 million auv or autonomous underwater vehicle belongs to the institute. This one is built to float. Every bit of weight added has to be counter balanced. Its little tiny tiny microglass spheres encased in epoxy. Oh, wow you cant see them. Larger glass spheres encase the technology. A computer on the bottom side of here that runs all the flight code tells the vehicle which way to g it keeps track of the mission, logs a lot of the data. Reporter with these battery s s, auv can stay down for 16 hours. While there, it also measures temperature. With those two measurements we can calculate the speed of sound and water, important measurement when were working with sonars. Reporter also on board mapping vehicle, instrument that you want working every time. Reporter to get the mission under way, a command is sent to the auv that gets picked up by this device. Once everything checks out and we have good navigation on the bottom well hit the go button. Reporter 80 to 100 feet deep, the java sea presents its own challenges. Huge swells could make retrieving the unit from the open water challenging. We have to get it close enough in to the ship to hook it but far enough away we dont want it bouncing off the ship. Theyve got it. Its locked in. Here we go. Reporter they can swap out Technology Based on the mission. That part has evolved with time. One thing that hasnt change sd each mission is a very slow process and then it takes time to doe download the data and then analyze it. Stephanie elam cnn, off the coast of california. This of course is david gallos specialty. Flight 447 and cnn analyst with us as well cnn aviation analyst and private pilot miles obrien. Indonesian authorities are trying to confirm they found what they think is the tail of the plane. Do we know exactly what is contained there, in terms of the black box . Is it the flight data recorder . What would be there . Well you know it depends on how much of the tail they got. On this version of the airbus 320, the black boxes are up a little bit further in the aircraft. It depends how much of that tail section they got. And hopefully, they did get a part of the tail section. Even that part has not been confirmed yet, anderson. Miles, there are thousands of this kind of airplane in use, the airbus a320. The idea this crash could have been because of a flaw is pretty scary, considering how many people are flying on these planes every single day. It make it is harder to understand why efforts to install Something LikeLive Streaming track rg moving so slowly. A lot of resistance to this anderson. I think, really when you get down to the bottom line it is the bottom line. Airlines dont want to spend the money. Its technologically possible to send out streams of data when an aircraft is in trouble. We would know all these important answers right now. Yes, the family tragedy is bad enough but there is the possibility that there is some kind of flaw that the whole world needs to know about right now. Airplanes are flying with them. And thats why this has to stop. You know david, i keep thinking about these divers rough conditions. You have huge swells on top, currents underneath. Zero visibility and all manner of twisted steel and debris that could cut a diver, seriously injure a diver, trap a diver. It would be horribly dangerous to be around a wreck like this with all the jagged edges as you say and even more so to enter it to find the black boxes or remove the bodies trapped inside. Its a horrible situation to be in. And, you know, its not something thats going to go away in a day or two. It will probably take days for the currents to settle down maybe even longer for visibility to improve. David doesnt some military aircraft have black boxes that essentially eject from the aircraft itself . They do. Why wouldnt civilian airliners do that as well if part of the danger for diver sincere to enter the wreck to get these boxes . Another good question. A fundamental misunderstanding what it takes to work beneath the surface of the sea. We talked last hour about how airasia was not licensed to fly on sunday four days during the week but not sunday the day the flight actually took off. You think this raises broader questions about how the airline itself was operating . I dont think its actual lyly going to be a direct, contributing cause to this accident that somehow this additional aircraft overwhelmed the air Traffic Control system and made it difficult for them to evade the weather. I dont buy that. But i do think it says an awful lot about how the Airline Might be operating and how the regulators may be operating, or not so well in that part of the world. You know aviation safety is all about a million tiny little technological things that you have to get right. You have to dot every i and cross every t. When you look at the face of things and see that theres an i that isnt dotted or theres a Weather Report that was nonstandard, all those things start to add up. And that begins to erode what we call aviation safety. David, in terms of the conditions obviously if its too dangerous for divers can robots can undersea vehicles can they be used . No. Its shallower water. Zero visibility is still zero visibility. Thats right, anderson. I thought initially our ov which has a cable attached to a ship would be okay. But its not. You have to hold a ship fairly still and under these conditions thats tough. With those currents at the bottom tough. Even with the auvs, like the one we saw in the clip those will get pushed around by currents. Theyre not equipped to handle highspeed currents like this its a catch 22 in many many ways. And the monsoon season lasts through till april. David gallos and miles obrien, appreciate it.

Tonight, a 7yearold girl is back with her family. Unfortunately she is not home. She, her sister piper, her cousin sierra and her parents were on their way home from key west. I heard no noise whatsoever. When she told me plane crash, of course i looked outside to see if there was any smoke or anything like that. No there was not. And so i brought her in the house and propped her feet up and called 911. And got ahold of a Police Officer and fortunately they were real close to the house. Tonight, sailor gutzlers hometown is in shock. George howell is there for us. Youre in illinois tonight. How is the community dealing with this . Reporter you know anderson it really is sort of a mix of emotions here in this town. On one hand people are celebrating what many call a miracle, the fact that this 7yearold girl that sailor gutzler managed to survive a plane crash and, at night, make her way through the brush and trees to find help. People are grateful shes alive. On the other hand look this is a community in mourning at the loss of the gutzler family and the fact that sailor must now grow up without her mother her father her sister and her cousin. And, really that affects people hew erin many different ways. This is a community where people take pride, small town in where people take pride in knowing each other. A town of about 3,200 people. I understand about a third of the population nearly 900 people attend the same Church Anderson the Trinity Lutheran church where Marty Gutzler attended church. Take a listen to what his pastor had to tell us this evening. This is a devastation for our community, a community can never, ever prepare for Something Like this. And we are were hurting. Were so saddened by the loss and are grieving the loss of marty and kim and piper and sierra as well. And this is just this is a blow to us. And, i mean have they already made plans for the funerals yet . Reporter yeah. Anderson, theyre planning that. Sierra wilders services will be held on wednesday. And the service for piper, kimberly and martin marty, they should all be held on friday but important to note anderson the family is expecting these to be private services. George howell appreciate that. I talked to sierras mom in the last hour sierra was 14. She died on that flight as well. Her mom described her as a little girl who loves spending time with her family loved being with her family more than anything. A fundraising site has been set up for sailor gutzler gutzler sailorgutzler fund. Com. Well put that on our website as well ac360. Com. What sailor is going through and what others in her situation have faced and what can overcome overcome. Reporter courage seen in those well beyond her young years. Thats what Larry Wilkins thought when sailor gutzler showed up on his front porch and told him an incredible story. She said my mom and dad are dead. We just had a plane crash. Reporter gutzler and her family took off from key west, florida, early friday. On board, her father who was piloting the twin engine aircraft along with her mother her 9yearold sister and 14yearold cousin. The plane ran into trouble and crashed in a wooded area in kentucky. Sailor was the only survivor. How was she able to survive the crash and then endure hiking threequarters of a mile through dark cold woods without shoes or warm clothes, still unknown. Little girl was she was amazingly composed for a 7yearold girl. Reporter her story of survival is rare but there are others documented in the cnn film sole survivor. In 1987 cecilia sheshaun was 4 years old, sole survivor of flight 255. 154 people were killed when the airline crashed on takeoff in detroit, including her entire family. Decades later, she still has scars and something more. I got this tattoo a reminder of where ive come from. Reporter she credits luck for her survival. Austin hatch believes a higher power may have helped him. God had his hand on me and i think it was a plan for my life. Reporter in 2003 when hatch was just 8 years old, the small plane his father was piloting crashed, killing his mother and siblings. Hatch and his father survived. Then tragically eight years later in 2011 hatch was in another crash. This time his father again the pilot, was killed as was his stepmother. Hatch was the only survivor. His brain injury so bad, he had to relearn to walk and even talk. Now just a few years after the second crash, he is on a basketball scholarship at the university of michigan and scored his first career points last month. Basketball has sort of has given me something to shoot for and its been my goal you know from when i woke up from the coma. What they all have in common is not just a shared tragedy be but a will to survive. Jason carroll, cnn, new york. Lets dig deeper. Were joined by the director of that film sole survivor. I find it interesting. Most of the survivors and sole survivors are either children or flight crew. Why kids . Its really a matter of physics, you know. Children have less body mass and, therefore, the impact is less great, theres less inertia and more survivable space. Theyre often protected by the seat. And so you know what we found is its really a matter of random chance but also just the physics of the situation. In terms of the crew members, they have more safety belts than the rest of the passengers. Did you find anything that linked the survivors together either in terms of how they survived however we just talked about how kids survive, but i guess more about the aftereffects of being a sole survivor . Yeah. After ward the number one thing that all survivors need is privacy. They need the ability to go back to a normal life. You know theres something that we found that we called it the double vacuum whereas quite often when you are a sole survivor its such an amazing, Human Interest story that it covers the news cycle for a long time. And that almost diverts the healing for the survivors. Because for a while, theyre distracted you know. And then all of a sudden when the Media Attention stops and the Public Interest stops its like another vacuum and they have to deal with the grief all over again, much later after the accident occurred. Do you find also a lot of to be labeled a miracle survivor thats a lot of pressure. Did you find anybody or people who were sole survivors who found trying to come up with what their reason in life was . Why did they survive and others not . Well you know it is interesting. One thing i was very surprised by when making the film is how often the survivors would say i dont like the word miracle. It adds a lot of pressure to their life. Suddenly they feel they need to come up with a cure for cancer or have some unparalleled reason for living. And so miracle, i think, can be a word that its sad with great intention, you know. Its a very loving thing to say, i think. Its coming from a good place but it puts a lot of pressure on survivors. And, you know one of the thing a lot of survivors struggled with is if you say they survived for a reason are you saying that everyone else didnt . And i think thats difficult for us to wrap our heads around. So with most of the sole survivors we dealt with in the film they pretty much have all come to the place that this is random chance. And also you talked to people who had been flight crew who had been pilots. Uhhuh yeah. Sure. Jim paul hanky was one of them com air flight 5191. The copilot . He was coatthe copilot yeah. And was there a special burden for him in that . Well that is an unbelievable burden. He wishes that he would have gone down with the ship. Every day of his life is truly a living hell where he wishes he would have died. And, you know, theres
